Ask HN: How would you change the HN stylesheet with 10 or less lines?

I know that Hacker News is about the community rather than the usability, and I know that the look has almost become iconic, but there is always part of me that wants to tweak the site a bit - maybe make it a little more mobile/touch friendly etc.<p>So many people before me have come up with great ideas but normally requiring a big change to the site (DOM etc), but I was wondering if we could make the smallest change, just a few lines to the css, what would the talent on HN come up with.<p>So here is your challenge if you choose to accept it this Saturday!:-<p>If you could add (or change) 10 lines in the HN css file, what would they be?
